Do not refit the VFD unless authorized; otherwise fire, electric shock or other
injury may occur.
The base of the radiator may become hot during running. Do not touch to avoid
hurt.
The electrical parts and components inside the VFD are electrostatic. Take
measurements to avoid electrostatic discharge during related operation.
1.4.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the braking optional parts (brake resistors, brake units or feedback
units) according to the wiring diagram.
Do not operate on the VFD if there is any damage or components loss to the
VFD.
Do not touch the VFD with wet items or body, otherwise electric shock may
occur.
Solid State motor overload protection reacts when reaches 150% of FLA.
Drives have no provision for motor over temperature protection.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the VFD and
avoid physical injury or death. For physical safety, the erector should take some mechanical
protective measurements, such as wearing exposure shoes and working uniforms.

TD310 Series VFD Safety precautions
-3-
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the VFD by its cover. The cover may fall off.
Install away from children and other public places.
The VFD cannot meet the requirements of lowvoltage protection in IEC61800-5-1 if the altitude of
installation site is above 2000m.
Use the VFD on appropriate condition (See chapter Installation Environment).
Don't allow screws, cables and other conductive items to fall inside the VFD.
The leakage current of the VFD may be above 3.5mA during operation. Proper and reliable
grounding is essential before connecting to power supply. Ground with proper techniques and
ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding conductor is the
same as that of the phase conductor (with the same cross sectional area).
R, S and T are the input terminals of the power supply, while U, V and W are the motor terminals.
Please connect the input power cables and motor cables with proper techniques; otherwise the
damage to the VFD may occur.
1.4.2 Commissioning and running
Disconnect all power supplies applied to the VFD before the terminal wiring and
wait for at least the designated time after disconnecting the power supply.
High voltage is present inside the VFD during running. Do not carry out any
operation except for the keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD and
motor.
The VFD cannot be used as “Emergency-stop device”.
The VFD cannot be used to break the motor suddenly. A mechanical braking
device should be provided.
Besides the above items, check to ensure the following ones before the
installation and maintenance during the running of the permanent synchronous
motor:
1. All input power supply is disconnected (including the main power supply and
the control power supply).
2. The permanent magnet synchronous motor has stopped running and
measured to ensure the output voltage of the VFD is less than 36V.
3. The waiting time of the permanent magnet synchronous motor after stopping
is no less than the time designated and measure to ensure the voltage
between + and –is less than 36V.
4. Ensure the permanent magnet synchronous motor does not rotate again
because of the external load. It is recommended to install effectively external
braking devices or disconnect the electric wiring between the motor and the
VFD directly.

Note:
Do not switch on or off the input power supply of the VFD frequently.
For VFDs that have been stored for a long time, check and fix the capacitance and try to run it
again before utilization (see Maintenance and Hardware Fault Diagnose).
Cover the front board before running, otherwise electric shock may occur.
1.4.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance, inspection,
and components replacement of the VFD.
Disconnect all power supplies to the VFD before the terminal wiring. Wait for at
least the time designated on the VFD after disconnection.
Take measures to avoid screws, cables and other conductive matters to fall
into the VFD during maintenance and component replacement.
Note:
Please select proper torque to tighten screws.
Keep the VFD, parts and components away from combustible materials during maintenance and
component replacement.
Do not carry out any isolation and pressure test on the VFD and do not measure the control
circuit of the VFD by megameter.
Carry out a sound anti-electrostatic protection to the VFD and its internal components during
maintenance and component replacement.

3.1 What this chapter contains
The chapter briefly describes the operation principle, product characteristics, layout, name plate and
type designation information.
3.2 Basic principles
TD310 series VFDs are wall or flange mountable devices for controlling asynchronous AC induction
motors and permanent magnet synchronous motors.
The diagram below shows the simplified main circuit diagram of the VFD. The rectifier converts
three-phase AC voltage to DC voltage. The capacitor bank of the intermediate circuit stabilizes the
DC voltage. The converter transforms the DC voltage back toAC voltage for theAC motor. The brake
pipe connects the external brake resistor to the intermediate DC circuit to consume the feedback
energy when the voltage in the circuit exceeds its maximum limit.

Note:
1. The input current of VFDs 0.75–55kW is detected when the input voltage is 220V and there is no
DC reactors and input/output reactors.
2. The rated output current is defined when the output voltage is 220V.
3. The output current cannot exceed the rated output current and the output power cannot exceed the
rated output power in the voltage range.

DC reactors and input/output reactors.
2. The input current of VFDs (220–500kW) is detected when the input voltage is 460V and there are
input reactors.
3. The rated output current is defined when the output voltage is 460V.
4. The output current cannot exceedthe rated output current and the output power cannot exceed the
rated output power in the voltage range.

Optional. The side cover will increase the protective degree
of the VFD. The internal temperature of the VFD will
increase, too, so it is necessary to derate the VFD at the
same time.

4 Installation guidelines
4.1 What this chapter contains
The chapter describes the mechanical installation and electric installation.
Only qualified electricians are allowed to carry out what described in this chapter.
Please operate as the instructions in Safety Precautions. Ignoring these may
cause physical injury or death or damage to the devices.
Ensure the power supply of the VFD is disconnected during the operation. Wait
for at least the time designated until the POWER indicator is off after the
disconnection if the power supply is applied. It is recommended to use the
multimeter to monitor that the DC bus voltage of the drive is under 36V.
The installation and design of the VFD should be complied with the requirement
of the local laws and regulations in the installation site. If the installation infringes
the requirement, our company will exempt from any responsibility. Additionally, if
users do not comply with the suggestion, some damage beyond the assured
maintenance range may occur.
4.2 Mechanical installation
4.2.1 Installation environment
The installation environment is the safeguard for a full performance and long-term stable functions of
the VFD. Check the installation environment as follows:
Environment
Conditions
Installation site
Indoor
Environment
temperature
–10–+50°C
If the ambient temperature of the VFD is above 40°C , derate according to the
detailed information of Appendix B.
It is not recommended to use the VFD if ambient temperature is above 50°C .
In order to improve the reliability of the device, do not use the VFD if the ambient
temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal ambient
temperature below the required one if the VFD is used in a closed space such as
in the control cabinet.
When the temperature is too low, if the VFD needs to restart to run after a long
stop, it is necessary to provide an external heating device to increase the internal
temperature, otherwise damage to the devices may occur.
Humidity
RH≤90%
No condensation is allowed.
The max relative humidity should be equal to or less than 60% in corrosive air.
